Everything you wanted to know about Dark Matter but were afraid to ask
Dark matter. It surrounds us and penetrates us; it binds the galaxy together. But what it is it really? Are we sure it exists at all? Can it really be explained by tiny invisible particles? I'll get you up to date on what we know so far about dark matter, how we're searching for it, and how it differs from the other big cosmic mystery of the day, dark energy. There will be time for questions at the end, so bring your own!
